Qt Commercial Editions

Several editions of Qt are available under a commercial license: Qt Console Edition, Qt Desktop Light Edition, and Qt Desktop Edition.

You may write commercial, proprietary, or otherwise non-free software only if you have purchased a commercial edition of Qt. If you purchase a commercial edition, you are entitled to technical support and upgrades.

If you want to develop Free or Open Source software for release using a recognized Open Source license, you can use the Qt Open Source Edition.
